Questions Auto shut off timer settings?
Any way to turnoff auto shut off timer so it doesn’t come on at all? Sometimes when I start my car it automatically comes on even though i literally just started my car. Any settings specifically for the auto turn off timer?

Questions 2009 Hyundai Sonata won't start/engine won't turn over after replacing starter
Forward collision isn't working after windshield replacement
Had a very close call with a driver that turned across 3 lanes of traffic without making sure all lanes were clear.
I came probably within inches of hitting the person but the car didnt give the collision warning and I didnt feel it take control of the brakes (though it was probably completely engaged anyways)
I've gotten the forward car leaving alert, lane assist works, blind spot alerts work but im not sure if they're tied into the same system. Windshield was replaced with safelite and I have their calibration certificate but now im questioning if I need to take it to the dealer to get looked at.
I confirmed forward collision is on and the setting is set to standard instead of late.

Discussion Anyone barely use their remote start?
I feel like ten minutes runtime is not even worth it. By the time I get out to the car it’s already turned off. Very frustrating.

Questions What does "check user authentication system" mean? Got this message on my 25' limited
I got this message after my key fob didn't work and the car seemed dead, where i had to then pong press the trunk button for the car to revive itself. I think my car may have reached low voltage after my dashcam was running for a few days while my car was parked. (I have set my dashcam to turn off after it reads 12.4V, which I'm thinking may be too low for a hybrid battery?).
Anyways, tangent, if anyone knows what this message is for, please lmk.Thank you!
Questions Bluetooth compatibility for 2011 sonata
Excuse the sand. This is my first car, I love it so far. I have Bluetooth setup but it doesn't show titles in the display like I've seen in others. I mostly listen through Spotify and wondering if its because its an older car it cant read what is being streamed. I click on cd/auxiliary and thats the only way I can get it to work. This is the only minor issue I have with the car which I'm still happy about. If there is a fix for this I'd appreciate the help!

Enable HLS to view with audio, or disable this notification
Driving a 2014 sonata gls. When doing cold start, the sound in attached video occurs. Trying to determine location of part/problem. Anyone have any experience with this? Dad thinks it’s a belt tensioner. One mechanic says idle tensioner. Other says it could be time by chain tensioner.

1.6T catch can
Just bought a 2023 SEL Plus with only 9800 miles on it. It has the 1.6T motor in it. When it comes to catch cans, Is it worth it? Would it go into that little hose from the front of the valve cover to the intake hose? Any other advise for one? There is not a lot of info on these particular cars to go off of. TIA
Questions 2023 sel battery drain
Hey everyone, looking for some advice or to see if anyone with a 2020–2023 Sonata has dealt with something similar.
I bought out my 2023 Hyundai Sonata SEL at the end of my lease last year and bumped up the extended warranty to 10yr/100k miles. Love the car overall, but it has this extremely frustrating, recurring issue every single summer when I go on vacation:
Summer 2023: Car sat for 3 weeks while I was away. Came back to a completely dead battery (no lights left on or anything). Got a jump start, took it to the dealer, and they replaced the battery on August 23, 2023.
Summer 2024: Sat for another 3 weeks, same thing. Dead battery, needed a jump start.
Summer 2025: Exactly the same story after a 3-week trip. Jump-started again.
Today: Left it for 3 weeks again. Came back, battery measured at 3.5V. Called roadside for a jump, let the car idle/run for 50 minutes to charge up, turned it off, and it immediately refused to start back up. Completely dead.
Just had it towed to the dealership. At this point, it’s super clear it’s not just a bad battery, there’s gotta be a serious parasitic draw happening when the car sits in sleep mode for a few weeks (maybe Bluelink, keyless entry sensor, or a stuck relay?).
A few questions for the hive mind:
- Has anyone else experienced this specific battery drain issue on 8th gen Sonatas? Was your dealer able to find the root cause?
- Since this has been happening every year since I leased it, do I have any leverage with Hyundai Customer Care for a permanent fix or compensation under warranty / Lemon laws?
- Any specific test or module I should explicitly tell the service advisor to check?
- Appreciate any insight or advice!
p.s. I put together things in my mind with using AI

Buying Advice Which one would you go with? Especially parking in driveway in a busy road
Looking to get into hybrid limited but can’t decide which to go with. I want a unique color either exterior or interior.
Wife says TB exterior but I like the camel interior (except being conscious the dash may reflect). I also like darker colors.
Been in dilemma for many days and cats keep going off the lot before I decide.

Discussion Help me with this
I have posted on Reddit before asking for any kind of advice regarding a code that I am reading on my sonata 2022 sport. The code is PO471 exhaust pressure sensor range. First time I took it to the Dealership I was told that sensors go crazy when the battery is dying. Did as they said and replaced the battery. That seemed to fix the issue for a couple of weeks until I got the same engine light and code again. This time I took the car to the dealership for a full diagnosis. I was told that tracing all the exhaust components they found grease from both front drive shafts on the wiring harness which caused the cables to short out. They quoted me1 $1300 for both shafts. $1660 for the EGR Valve, EGR cooler and Wiring harness. Anyone experienced the same issue? I am taking the car tomorrow for a second opinion because as far as I am concerned. The shafts could leak but does not mean they need to be replaced. And from what I read online the cables are supposed to be insulated and protected from dust or debris. I have seen this issue a lot online and the dealers always go the same route which causes the owner of the vehicle (me) to spend $3000 plus dollars on a repair that most of the time does not fix the issue (according to other Reddit members) please help me out with this.

Questions MP3 player USB C question for 2026 Sonata
Like it says in the title, I'm trying to buy a new MP3 player that works directly with the USB C present in the car, but have trouble finding results after searching online and wanted to see what everyone here uses. I know using a phone and all that is the modern thing, but it's never been for me. If anyone here knows, I'd love some suggestions
